摘要：
A reconfigurable dual-passband to single-passband filter, which is based on miniaturized ring resonators, is presented. The filter is designed for 448 MHz and 668 MHz as the central passband frequencies. Simulations are used for enhancing the design. The lower passband can be eliminated by just changing the location of a short. The filter is implemented using microstrip technology on a RO3010 substrate with thickness of 1.28 mm. Measurements for the optional eliminated band are in good agreement with the expected values. The transmission is -3 dB at the central frequency for dual-passband configuration and -26 dB for single-passband configuration.
